ELIAS T. FORD, OF STILLWATER, NEW YORK.

Letters Patent No. 92,438, dated July 13, 1869.

IMPROVEMENT `IN CARRIAGE-WRENCH.

The Schedule referred to in these Letters Patent and making part of the saine.

To all @whom it ma/ z/ concern:

Be it know that I, ELIAS T. FORD, of the town of Stillwater, county of Saratoga, and State of New York, have invented new and usetiil Improvements'in a Oarriage-Wrench,used for handling the axle-nut, as coupled The nature of my invention consists in the construction of a wrench, consisting of a frame, with a movable or adjustable double socket, mounted upon guide-arms, embracing the axle-nut, and operated by a tensionscrew, the guide-arms, with hooks placed upon 'two spokes, and upon either side of the hub.,composing the wheel, and s'o arranged and connected as to couple the axle-nut and hub of carriage or wagonwheels, holding the same snugly together, while the wheel, with the axle-nut, is turned off and on the axle, for the purpose of lubricating the axle, without coming in contact with the greasy nut, and blackening the hands ofthe operator.

The wheel acts as its own balance in its rotation, perfbrming its own revolution with axlenut, when set in motion, while the axle is elevated with a jack, thereby effecting a saving of time and labor over the ordinary hand-method.

Figure 1, in the drawings, represents a perspective View of my invention, when attached to a carriagewheel. Y

Figure 2 is a view,in perspective, of my wrench.

Figures 3, 5, and 6, are views of detached portions of the wrench.

Figure 4 represents a portion of the axle, with bearing B and uut L. v

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Construction.

F F representthe guide-arms, connected to the cross-head O, thus constructed, form the frame of the wrench.

The left extremities of each` guide-arm F are {iatteiied, then curved in form of hooks, and covered with soft rubber or leather, upon the inner surface.

Through the orifice made at the centre and through the rear head 0, I insert the tension-screw J. -A correspondingV thread is cut to match the screw J, which is seen `in gs. 5 and 6.

The run of the screw J is parallel with the guidearms F F.

Fig. 5 shows the form of the movable socket D, with cross-bar H, and' constructed therewith, and provided with the slots or recesses e e, out with each extremity of the same.

The front end of the tension-screw J is made smaller, and formed with a shoulder next to the thread, and provided with a pin, a, as seen in iig. 6.

The smaller portion or journal of the screw J receives the socket D, an orifice being made within the centre of socket D for the'reception of the screw-journal a, as the cross-bar H, with double socket D, is located within the fram'eC FF, and the recesses e are adjusted upon the guide-arms F F, as also seen arranged in iig. 2.

The double socket D, with cross-bar H, is ysecured to the screw J, by means of the pin a at the same time the journal of the screw J is permittedto turn right and left, within the orifice of the socket D. A nut may be used as a substitute for the pin a.

The cavities, t t, constituting the double sockets, of

section D H, may vary, one to be larger than the other, thereby furnishing two sizes, to suit the different sizes of the axle-nuts, and the section D H may be taken out of' the frame O F, and the socket turned over for that purpose.

'- The nut-cavities, or sockets t tare double, as seen in figs. 3 and 5. One end may be closed, (seen in iig.

3,) or both ends may be constructed open at the sides, as seen in fig. 5.

Operation.

I now take the wrench, as seen in tlg. 2, and arrange and connect 'it to the wheel A, by placing the hooks 'v c over two spokes, upon each side of the hub,-

seleoting the two that are upon aline with each other, and centre of the wheel, 4at the same time adjusting the socket D upon the axle-nut L, by turning the screw J to the right,.thereby bringing together the hub B and axle-nut L; a tension or a contraction is tated in the opposite direction. The thread of the nut not having been moved, catches or enters the thread upon the axle, and continues to move itself and wheel A to t eir proper positions upon the axle M. The wrench is then removedv by reversing .the screw J, thereby drawing back the socketvD with the bar H, moving upon the guide-armsF F, relieving the pressure between the hub and nut, thus producing an easy movement, a saving of time, and without soiling or blackening thc hands of' the operator.

What I claim, and desire to secure by Letters Patent, is

l. The socket D, cross-bar H, arms F, andscrew J, arranged and operated as described, and for the purpose set forth.

.2. The frame, composed of the guide-arms F F,.an,d cross-head G, when used in connection with the double `produced by the screw J, holding the two snugly tosocket D, cross-bar H, and screw J, the whole con J. MGKENNEY, WM. A. MCKENNEY.
